Description: |
In findings of relevance to conservationists and the fishing industry, new research links short-term reductions in growth and reproduction of marine animals off the California coast to increasing variability in the strength of coastal upwelling currents - currents that supply nutrients to the region's diverse ecosystem. The new study shows that since 1950 the California coast has experienced winters with extremely weak upwelling more frequently than in the previous five centuries.
